Compelling questions about the Cretaceous Period

Self-guided, inquiry-based exercises using open-ended questions allow students to explore a scientifically significant question in their own way focusing on their interests.

For each compelling question suggested exploration pathways are proposed to guide further questioning and discovery of information.
